The current supported version of SMF is 1.1.7 right? There is no installation instruction for this ad mod for 1.1.7?

I saw someone suggest just editing the .xml package file, repackaging and installing the mod that way and everything should be fine? I did that, and the installation said it completed successfully. However I don't see any ads anwhere after having done the install.

It looked to me like the installer attempted to make the file edits, but not all of them were made. I'm guessing because some of the "After" (text / code to search for) doesn't exist.

For example, the "File Edits" section of the install says to search for:

Anyway, I really want to run a simple forum and display some ads. Should I install a different version of SMF? Should I look for alternate installation instructions for this mod on 1.1.7 for the default theme?
